Amino molding compound is a polymer material with excellent physical properties and chemical stability, which is widely used in electronics, automobiles, aerospace and other fields. The production process of amino molding compound mainly includes raw material preparation, reaction preparation, molding processing and post-processing. Today Johnly Factory will share with you the production process of amino molding plastic.
1. Raw material preparation is the first step in the production of amino molding compound. The main raw materials of amino molding compound are isocyanate and polyether polyol, among which isocyanate is a kind of toxic and harmful substance, which needs to be stored and used in special equipment. Polyether polyols require fine screening and proportioning to ensure product quality and performance.
2. Reaction preparation is the core link in the production of amino molding compounds. The reaction preparation mainly includes the mixed reaction of isocyanate and polyether polyol. The reaction process needs to be carried out under a certain temperature and pressure, and auxiliary agents such as catalysts and stabilizers need to be added at the same time. After the reaction, it needs to be processed such as demoulding and drying to obtain the finished product.
3. Molding is an important link in the production of amino molding compounds. Molding mainly includes various methods such as injection molding, extrusion, compression molding, etc. Different molding methods are suitable for different products and process requirements. Molding needs to be carried out under a certain temperature and pressure, and parameters such as molding time and molding pressure need to be controlled to ensure the quality and performance of the product.
4. Aftertreatment is the final step in the production of amino molding compounds. Post-processing mainly includes cleaning, inspection, packaging and other links. Strict inspection and testing of finished products are required to ensure product quality and performance. At the same time, the finished product needs to be packaged and stored to prevent the product from being affected by the external environment.
The production process of amino molding compound is a complicated process, and every link needs to be strictly controlled to ensure the quality and performance of the product. With the continuous advancement of science and technology and continuous improvement of technology, the application range of amino molding compounds will become wider and wider, bringing more convenience and benefits to human production and life.
